Step 1: General Setup

1a) Adjust primary colors (see Matching Colors in Multiple Screens) to ensure matched overall color temperatures and light output between screens.

IMPORTANT

Double-check that all WHITES and LIGHT OUTPUT are well-matched.

1b) Enable the Brightness Uniformity checkbox. This will enable access to the uniformity controls and will apply the settings to your image.

1c) Select the 13 Point test pattern for display. This pattern provides 9 screen “zones” with 13 targets.

FOR BEST RESULTS: Rather than examining the CENTER of each zone when assessing Brightness Uniformity adjustments, focus on extreme EDGES as indicated in the illustration at right.

1d) In either Color Adjustments menu, select a “User” color. Then:

•If you have created a “User 1” color gamut (recommended) for a well- matched wall, continue to Step 1e.

•If you prefer maximum brightness rather than a particular color temperature, select “Max Drives”.

IMPORTANT

Do not change User 1 Color Adjustment

in color-matched applications!

1e) In the White Uniformity menu, set the “Overall” output level to 50.0 and all remaining slidebars to 0.0. This decreases the light output just enough throughout the screen so that any color level can then be

increased later as necessary for matching light output

from zone-to-zone. Do not

exceed 50.0 for “Overall”—a higher level will likely interfere with achieving brightness uniformity and is not recommended.
